Greeks get ideas from other culture through trade, because it was their fundamental characteristic. The earliest recorded trade exchange dates back from as early as Bronze Age where pottery, gold, copper and ivory were traded between Asia Minor, Cyprus, Crete, Cyclades and Egypt for luxury items and raw materials.
Although, their trade lessened during the Dark Ages from 11th to 8th century BCE, because it was the Phoenicians who principally carried out the trade in most of these places. It grew back during 8th century BCE where the demand for international trade had increased. Through trade, they were able to adapt different ideas from other cultures and one of these ideas includes their Greek alphabet wherein its elements were adapted from the Phoenicians.
